effective use of digital libraries demands maintenance of bibliographic databases. Especially, the reference fields of academic papers are full of useful bibliographic information. We, therefore, proposed a method of automatically extracting bibliographic information from reference strings using a conditional random field (CRF). However, at least a few hundred reference strings are necessary for training the CRF to achieve high extraction accuracies and the preparation of such human-labeled data for training is usually expensive. As described herein, we propose the use of active sampling, pseudo-training data and transfer learning to improve extraction accuracies with a small amount of training data. Then we evaluate the extraction accuracies and the associated training costs by experimentation and discuss the effectiveness of the proposed approach.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"29","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"18","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"8"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":142628,"links":{}}
